Brush Type Automatic Backwash Filtration System For Wastewater Cooling Water

Brush type automatic self-cleaning filter wastewater, cooling water automatic backwashing filtration system

 
Describe

The liquid enters the body filter through the inlet to filter, the liquid is filtered by the filter element, the impurities in the liquid are deposited on the stainless steel filter screen, when the inlet pressure and outlet pressure reach the set value; the system automatically starts the self-cleaning program; the sensor sends the information It is transmitted to the power distribution system, and the power distribution system receives the pressure signal to trigger: the electric motor drives the brush to rotate to clean the filter element; at the same time, the sewage valve opens to discharge the sewage; the cleaning time is 10-60 seconds (settable), and the valve closes when the cleaning ends; The motor stops running; the system returns to the initial state; it begins to enter the next filtration process.

Working principle
The filter workflow is divided into filtering state and backwashing sewage state
1. Under normal filtration state: the liquid enters the body from the liquid inlet and is filtered by the filter element, the impurities in the liquid are deposited on the filter screen, the filtered liquid is discharged from the body liquid outlet, and the sewage valve is in a closed state;
2. Backwashing sewage state: After the filter device has passed through N multiple normal filtration processes; the impurities in the liquid are deposited on the filter screen, when the inlet pressure and the outlet pressure reach a certain differential pressure value (≥0.5MPa); the filter device is here When the backflush is required; the intelligent pressure sensor transmits information to the power distribution system; the power distribution system is running; the drain valve is automatically opened; the backwash rotating arm intelligently rotates, causing the backwash node plate to rotate 360 degrees in the direction indicated by the arrow (stop), Under the action of the pressure difference; the filter elements are backwashed one by one; the dirt inside the filter element is backwashed and discharged through the sewage outlet under the working condition of reaction force; the backwashing process ends; the sewage valve is automatically closed; the equipment enters normal filtration state.

Advantage
1. Fully automatic intelligent control
2. Small size, large flow, high precision
3. Intelligent online backflushing does not stop and flow continuously;
4. The body replaces the filter element, quick-plug design, easy to replace;
5. Multi-filter element structure; precision can be adjusted;
6. It can be installed vertically/horizontally, which significantly saves installation space
7. The filter element has an online recoil precision of 5 microns, which can be used repeatedly.
